nginx-module-vts 是一个很不错的nginx 模块，我们可以用来，方便的分析系统的请求状态
同时支持基于prometheus 的监控, 我参考openresty 的docker镜像已经制作了一个集成模块
的镜像 dalongrong/openresty-nginx-module-vts
环境准备
- docker-compose 文件
version: "3"
services:
api:
build: ./
image: dalongrong/demo-ngx-vts
ports:
- "8080:80"
g:
image: grafana/grafana
ports:
- "3000:3000"
p:
image: prom/prometheus
volumes:
- "./prometheus.yml:/etc/prometheus/prometheus.yml"
ports:
- "9090:9090"- 集成nginx-module-vts的openresty 配置

}
}
- prometheus监控配置
prometheus.yml
scrape_configs:
- job_name: nginx
metrics_path: /status/format/prometheus
static_configs:
- targets: ['api:80']启动&&集成测试
- 启动
docker-compose up -d- 界面效果
- 集成grafana
添加prometheus datasource 配置
添加dashboard
说明
nginx-module-vts 是一个很方便的模块，集成进openresty 中，我们可以快速的实现系统的信息监控，同时模块的文档也很全，类似的也
有一个基于opentracing 的模块nginx-opentracing
